The embodiments described below with reference to the accompanying drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

In order to make the technical solution of the present invention better understood, the following description will be made with reference to the accompanying drawings in the embodiments of the present invention, and the technical solution in the embodiments of the present invention will be described clearly and completely. It is to be understood that the disclosed embodiments are merely exemplary of the invention, and are not intended to limit the invention to the precise embodiments disclosed. Based on the embodiments in the present invention, all other embodiments obtained by the person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Referring to fig. 1, an embodiment of the present invention provides a damping pad 100, where the damping pad 100 can perform damping and noise reduction functions. For example, the damping pad 100 may be applied to the water pump assembly 10 in the water purifying device 1, when installed, the water pump 300 may be installed on the installation bracket 200, and the installation bracket 200 may be installed on the housing 50 through the damping pad 100, so that the damping pad 100 helps to reduce the transmission of the vibration generated by the water pump 300 to the housing 50 through the installation bracket 200, thereby reducing vibration and noise and improving the use experience of a user.

The damping pad 100 may be made of rubber, nylon, sponge or other elastic materials, which is helpful for the damping pad 100 to deform when bearing a load, thereby playing a damping role.

Referring to fig. 2 to 4, the damping pad 100 includes a main body 110 and a supporting portion 130, the main body 110 has a mounting through hole 111, and the mounting through hole 111 can be matched with a fixing member, so that the damping pad 100 can be fixed with other structures through the fixing member. The fasteners may be bolts, screws, etc. The body portion 110 may be generally in the shape of a circular cylinder. In other embodiments, the main body 110 may be provided in other shapes.

The supporting portion 130 is connected to the outer peripheral surface of the main body portion 110, the supporting portion 130 has an outer surface 131 located on a side away from the main body portion 110, and the supporting portion 130 is provided with a locking groove 133 penetrating through the outer surface 131. Thus, the damping pad 100 can be clamped to other structural members through the clamping groove 133. For example, the mounting bracket 200 is provided with a through hole 231, and the damping pad 100 can be inserted into the through hole 231 through elastic deformation of the damping pad itself, so that the side wall of the through hole can be clamped in the clamping groove 133. As such, the supporting portion 130 may function to support the mounting bracket 200. When the support 130 receives an axial load, it can be bent by itself, thereby achieving an effect of axial vibration reduction.

The width of the catching groove 133 in the axial direction of the mounting through-hole 111 gradually decreases from the main body portion 110 toward the outer surface 131. In this way, the supporting portion 130 can be bent and deformed at a larger angle, so as to improve the axial damping effect of the damping pad 100. For example, when the mounting bracket 200 is snapped into the snap groove 133, it will be appreciated that at least one damping chamber is formed between the mounting bracket 200 and the support portion 130. Thus, the vibration generated by the operation of the water pump 300 is transmitted to the damping pad 100 through the mounting bracket 200, and when the supporting portion 130 is subjected to the axial vibration transmitted by the mounting bracket 200, the volume of the damping cavity between the mounting bracket 200 and the supporting portion 130 is gradually reduced, so that the supporting portion 130 can be bent and deformed at a larger angle, and the axial damping effect of the damping pad 100 is improved.

The support portion 130 may be substantially annular and may be disposed around the outer circumferential surface of the body portion 110. In other embodiments, the supporting portion 130 may be provided in other shapes.

In some embodiments, the connection position of the supporting portion 130 and the main body portion 110 may be a circular arc transition. Therefore, the cracking of the joint of the support part 130 and the main body part 110 when the support part 130 is bent under force can be improved, and the stress concentration of the joint of the support part 130 and the main body part 110 can also be improved. In other embodiments, the connecting position of the supporting portion 130 and the main body portion 110 may also adopt a chamfered transition.

In some embodiments, the supporting portion 130 may include a first supporting portion 135 and a second supporting portion 137 that are oppositely disposed, and the first supporting portion 135 and the second supporting portion 137 are spaced to form the locking groove 133. The card slot 133 may be a generally annular card slot and is disposed about the body portion 110.

The catching groove 133 may include a first vibration reduction groove 1333, a mounting groove 1331, and a second vibration reduction groove 1335 that are sequentially communicated in the axial direction of the mounting through hole 111, the first vibration reduction groove 1333 being gradually reduced in width in the axial direction of the mounting through hole 111 from the main body part 110 toward the outer surface 131, and the second vibration reduction groove 1335 being also gradually reduced in width in the axial direction of the mounting through hole 111 from the main body part 110 toward the outer surface 131. Thus, the vibration damping effect of the vibration damping pad 100 on both sides in the axial direction is improved. For example, the first supporting portion 135 and the second supporting portion 137 form a mounting groove 1331 at an interval, and the mounting bracket 200 may be snapped into the mounting groove 1331. A surface of the first support portion 135 facing the second support portion 137 and the main body portion 110 cooperate to form a first vibration reduction groove 1333. In this way, when the damping pad 100 bears the bearing load, the first damping groove 1333 helps the first supporting portion 135 to generate bending deformation at a larger angle when bearing the axial load, thereby improving the axial damping effect of the damping pad 100. The surface of the second support part 137 facing the first support part 135 and the main body part 110 cooperate to form a second damping groove 1335, so that the second damping groove 1335 helps the second support part 137 to generate a larger-angle bending deformation when bearing an axial load, and the axial damping effect of the damping pad 100 is improved.

In some embodiments, first support 135 includes a first end portion 1351 and a second end portion 1353, first end portion 1351 is coupled to body portion 110, second end portion 1353 faces away from body portion 110, second end portion 1353 is provided with a first protrusion 139, first protrusion 139 protrudes toward second support 137. Thus, the first protrusion 139 may replace the surface of the first support portion 135 facing the second support portion 137 to abut against the mounting bracket 200, when the first support portion 135 is subjected to an axial load, the first protrusion 139 may space the surface of the first support portion 135 facing the second support portion 137 from the mounting bracket 200, reduce the contact area between the first support portion 135 and the mounting bracket 200, increase the volume of the first damping groove 1333, so that the first support portion 135 may be bent and deformed at a larger angle when being subjected to the axial load, thereby improving the axial damping effect of the damping pad 100.

The first protrusion 139 may be wound around a side of the first support 135 facing the second support 137. Alternatively, the number of the first protrusions 139 may be multiple, and the multiple first protrusions 139 are distributed on one side of the first supporting portion 135 facing the second supporting portion 137. The cross-sectional shape of the first protrusion 139 may be rectangular, semicircular, trapezoidal, or other shapes.

In some embodiments, the thickness of the first support 135 may gradually decrease from the first end 1351 to the second end 1353. Thus, the connecting area between the first supporting portion 135 and the main body portion 110 is increased, which is beneficial to increasing the connecting strength between the first supporting portion 135 and the main body portion 110, so that the first supporting portion 135 can provide larger supporting force, and meanwhile, the first supporting portion 135 can better participate in bending deformation when bearing axial load, and the included angle between the outer surface 131 of the first supporting portion 135 and the outer peripheral surface of the main body portion 110 can be larger than 90 degrees, which is beneficial to avoiding the condition of stress concentration at the connecting part of the outer side of the first supporting portion 135 and the main body portion 110. In other embodiments, the thickness of the first support 135 may also be constant from the first end 1351 to the second end 1353.

In some embodiments, the second supporting portion 137 includes a third end portion 1371 and a fourth end portion 1373, the third end portion 1371 is connected to the main body portion 110, the fourth end portion 1373 faces away from the main body portion 110, the fourth end portion 1373 is provided with a second protrusion 141, and the second protrusion 141 protrudes toward the first supporting portion 135 and is opposite to the first protrusion 139. Thus, the second protrusion 141 may replace the surface of the second support portion 137 facing the first support portion 135 to abut against the mounting bracket 200, when the damping pad 100 is subjected to an axial load, the second protrusion 141 may space the surface of the second support portion 137 facing the first support portion 135 from the mounting bracket 200, reduce the contact area between the second support portion 137 and the mounting bracket 200, increase the volume of the second damping groove 1335, so that the second support portion 137 may be bent and deformed at a larger angle when being subjected to the axial load, thereby improving the axial damping effect of the damping pad 100.

Through setting up first arch 139 and second arch 141 for when damping pad 100 bore axial load, first arch 139 and second arch 141 can the butt in the both sides that carry on the back of the body of installing support 200, and first supporting part 135 and second supporting part 137 all can produce bending deformation with bigger angle, thereby play the effect of damping, have promoted the axial damping effect of damping pad 100.

In some embodiments, the thickness of the second support 137 may gradually decrease from the third end 1371 to the fourth end 1373. In this way, the connection area between the second support portion 137 and the main body portion 110 is increased, which helps to increase the connection strength between the second support portion 137 and the main body portion 110, so that the second support portion 137 can provide a greater support force, and the second support portion 137 can better participate in bending deformation when bearing an axial load. Moreover, the included angle between the outer surface 131 of the second supporting portion 137 and the outer peripheral surface of the main body portion 110 may be greater than 90 °, which helps to avoid stress concentration at the connection between the outer side of the second supporting portion 137 and the main body portion 110. In other embodiments, the thickness of the second supporting portion 137 may be constant from the third end portion 1371 to the fourth end portion 1373.

In some embodiments, the mounting through-hole 111 may include a first mounting hole 1111, a damping hole 1113, and a second mounting hole 1115 that are sequentially communicated, and the diameters of the first mounting hole 1111 and the second mounting hole 1115 may be substantially equal. First mounting holes 1111 and second mounting holes 1115 may be used to mount fasteners.

The diameters of the first mounting hole 1111 and the second mounting hole 1115 are smaller than the diameter of the damping hole 1113. In this manner, when the fixing member is installed in the installation through hole 111, an annular damping cavity may be formed between the outer circumferential surface of the fixing member and the inner wall of the damping hole 1113, and the annular damping cavity may be used to reduce the radial load borne by the damping pad 100. For example, the card slot 133 is located between the first mounting hole 1111 and the second mounting hole 1115 in the axial direction of the mounting through hole 111, and is opposite to the vibration reduction hole 1113. So, when the vibration that water pump 300 produced transmitted to installing support 200, installing support 200 transmitted for damping pad 100 radial load through the inner wall of draw-in groove 133, and at this moment, damping pad 100 radially produced bending deformation to extrude annular damping chamber, make the volume in annular damping chamber reduce, damping pad 100 radially can produce bending deformation of bigger angle, thereby play the effect of bradyseism, promoted damping pad 100's radial damping effect. For example, the locking groove 133 and the damping hole 1113 may be oppositely disposed on opposite sides of the sidewall of the main body 110.

In addition, when the radial load applied to the damping pad 100 by the mounting bracket 200 is large, the inner wall of the damping hole 1113 may abut against the fixing element to perform a limiting protection function, which helps to avoid the interference between the water pump 300 and other components due to the large radial load.

In some embodiments, the junction of the inner walls of the first mounting hole 1111 and the damping hole 1113 and the junction of the inner walls of the second mounting hole 1115 and the damping hole 1113 may be chamfered. For example, the vibration damping pad 100 may include a first inner circumferential surface around which the first mounting hole 1111 is formed, a second inner circumferential surface around which the vibration damping hole 1113 is formed, and a third inner circumferential surface around which the second mounting hole 1115 is formed, the diameters of the first and third inner circumferential surfaces may be equal, and the diameters of the first and third inner circumferential surfaces may be smaller than the diameter of the second inner circumferential surface. It will be understood that the first step surface is formed between the first inner peripheral surface and the second inner peripheral surface, and the first step surface may be a conical surface inclined with respect to the axis of the mounting through hole 111, which helps to avoid the right-angle connection between the first step surface and the first inner peripheral surface, so that the thickness between the connection point of the first step surface and the first inner peripheral surface and the outer surface of the damping pad 100 is relatively thin, which results in the damping pad 100 being easily damaged. In addition, a second step surface may be formed between the third inner circumferential surface and the second inner circumferential surface, and the second step surface may be a conical surface inclined with respect to the axis of the mounting through hole 111, so as to help avoid a right-angle transition between the second step surface and the second inner circumferential surface, so that the thickness between the joint of the second step surface and the second inner circumferential surface and the outer surface of the damping pad 100 is relatively thin, which may result in a situation that the damping pad 100 is easily damaged.

In some embodiments, the supporting portion 130 may further include a first inner surface 143, a second inner surface 145, and a third inner surface 147, the first inner surface 143 and the second inner surface 145 are respectively disposed on the first supporting portion 135 and the second supporting portion 137 and are oppositely disposed, the third inner surface 147 is connected between the first inner surface 143 and the second inner surface 145, the first inner surface 143, the second inner surface 145, and the third inner surface 147 are connected to form the locking groove 133, and a distance from the third inner surface 147 to an axis of the mounting through hole 111 is greater than a distance from an outer circumferential surface of the main body portion 110 to the axis of the mounting through hole 111. In this way, the diameter of the third inner surface 147 may be larger than the diameter of the outer circumferential surface of the main body portion 110, so that the damping hole 1113 may be designed to have a larger diameter to improve the radial damping effect of the damping pad 100, and also to help avoid the damping pad 100 from being easily damaged due to the thin thickness between the third inner surface 147 and the inner wall of the damping hole 1113. Further, the damping hole 1113 and the third inner surface 147 may be disposed opposite to each other on both the inner and outer sides of the body portion 110.

The first inner surface 143 and the third inner surface 147 may be in a circular arc transition, which is helpful to improve the situation that the first inner surface 143 and the third inner surface 147 crack when the first supporting portion 135 is bent under a force, and also improve the situation that the stress is concentrated at the joint of the first inner surface 143 and the third inner surface 147. In other embodiments, a chamfered transition may be used between the first inner surface 143 and the third inner surface 147.

The second inner surface 145 and the third inner surface 147 may also be in a circular arc transition, which is helpful to improve the situation that the second inner surface 145 and the third inner surface 147 crack when the second supporting portion 137 is bent under a force, and also improve the situation that the stress is concentrated at the joint of the second inner surface 145 and the third inner surface 147. In other embodiments, a chamfered transition may be used between second inner surface 145 and third inner surface 147.

In some embodiments, the included angle between the first inner surface 143 and the third inner surface 147 may be less than 90 °, and thus, a first damping groove 1333 may be formed between the first inner surface 143 and the third inner surface 147. An included angle between the second inner surface 145 and the third inner surface 147 may be less than 90 °, and thus, a second damping groove 1335 may be formed between the second inner surface 145 and the third inner surface 147.

In some embodiments, the first mounting hole 1111 and the second mounting hole 1115 may be symmetrically disposed, and the first supporting portion 135 and the second supporting portion 137 may also be symmetrically disposed. Specifically, the first and second mounting holes 1111 and 1115 may be centrally symmetrical with respect to the center of the body part 110, and the first and second support parts 135 and 137 may be centrally symmetrical with respect to the center of the body part 110. Therefore, the installation direction of the damping pad 100 does not need to be distinguished during installation, and the production efficiency is improved. In addition, because the first mounting hole 1111 and the second mounting hole 1115 are disposed at both ends of the vibration damping pad 100, both ends of the vibration damping pad 100 can be stressed when the fixing member is mounted, so that the vibration damping pad 100 can simultaneously satisfy a plurality of mounting methods such as horizontal mounting, vertical mounting, inclined mounting, and the like, thereby increasing application scenarios of the vibration damping pad 100.

Referring to fig. 1 to 2, the embodiment of the present invention further provides a water pump assembly 10, where the water pump assembly 10 includes a mounting bracket 200, a water pump 300, and a damping pad 100 according to any of the above embodiments.

The diameter of the third inner surface 147 may be equal to or slightly larger than the diameter of the through-hole 231, helping to avoid the vibration damping pad 100 from wobbling within the through-hole 231.
